The leader of Greenland has instructed the island's 57,000 residents to prepare for a possible American invasion, an unprecedented warning that underscores how seriously authorities are taking President Donald Trump's territorial ambitions in the Arctic.
The stark advisory came as Greenlanders have adopted red baseball caps emblazoned with "Make America Go Away" as a symbol of defiance against U.S. pressure, according to Reuters reporting from the capital, Nuuk.
The autonomous Danish territory finds itself at the center of an escalating geopolitical crisis after Trump publicly declared his intention to purchase Greenland for $700 billion—a proposal that Danish Prime Minister Mette Frederiksen rejected as "absurd" when first raised during Trump's previous presidency in 2019.
This time, however, the American president has not accepted refusal. Washington has threatened 10 percent tariffs on eight European nations, including Denmark, beginning February 1, with escalation to 25 percent by June if they continue opposing American control of the island. Trump has also shared altered maps on social media showing the U.S. flag covering Greenland, Canada, and Venezuela.
The island's strategic value has increased dramatically as climate change opens new Arctic shipping routes and reveals mineral deposits including rare earth elements critical to modern technology. Greenland also hosts Pituffik Space Base (formerly ), a crucial American early-warning radar installation.
